When? Long ago. Ten thousand days. The crash victims hid in the cliffs from the sun. Fire, ice and floods washed away the wreckage of the huge metal seeds. The victims were shaped and beaten like iron upon a forge. Solar radiations drenched them. Their pulses quickened, two hundred, five hundred, a thousand beats a minute. Their skins thickened, their blood changed. Old age came rushing. Children were born in the caves. Swifter, swifter, swifter the process. Like all this world's wild life, the men and women from the crash lived and died in a week, leaving children to do likewise. So this is life, thought Sim. It was not spoken in his mind, for he knew no words, he knew only images, old memory, an awareness, a telepathy that could penetrate flesh, rock, metal. So I'm the five thousandth in a long line of futile sons? What can I do to save myself from dying eight days from now? Is there escape? His eyes widened, another image came to focus. Beyond this valley of cliffs, on a low mountain lay a perfect, unscarred metal seed. A metal ship, not rusted or touched by the avalanches. The ship was deserted, whole, intact. It was the only ship of all these that had crashed that was still a unit, still usable. But it was so far away. There was no one in it to help. This ship, then, on the far mountain, was the destiny toward which he would grow. There was his only hope of escape. His mind flexed. In this cliff, deep down in a confinement of solitude, worked a handful of scientists. To these men, when he was old enough and wise enough, he must go. They, too, dreamed of escape, of long life, of green valleys and temperate weathers. They, too, stared longingly at that distant ship upon its high mountain, its metal so perfect it did not rust or age. The cliff groaned. Sim's father lifted his eroded, lifeless face. "Dawn's coming," he said. II Morning relaxed the mighty granite cliff muscles. It was the time of the Avalanche. The tunnels echoed to running bare feet. Adults, children pushed with eager, hungry eyes toward the outside dawn. From far out, Sim heard a rumble of rock, a scream, a silence. Avalanches fell into valley. Stones that had been biding their time, not quite ready to fall, for a million years let go their bulks, and where they had begun their journey as single boulders they smashed upon the valley floor in a thousand shrapnels and friction-heated nuggets. Every morning at least one person was caught in the downpour. The cliff people dared the avalanches. It added one more excitement to their lives, already too short, too headlong, too dangerous.
